To all w/wmz'tmrmy concern',

Be it known that I, .IAoon DiNnnLAonnR, a citizen voi" the United States, residing at I-Iazleton, in the countyof Luzernel and Stateof Pennsylvania., have invented certain new and useful Improvements in Horseshoe Calks, of which the rifollowingkis a specification. f i

This invention relates to gan improved horseshoe calk and has as. one of its principal objectsA to providey ay device of this character which will eiiectually prevent slip? ping of a horse when traveling` over oiled roads or icy surfaces.y y y y A further object of thek invention is to provide a calk which may be readily applied and which, if desiredmay be removed.

And the invention has as a still further object to provide acalk employing a locking key for securing the" calk in position upon the shoe andwherein the calk will be so formed that, whenk the key is applied, the'key will be bent longitudinally and thus prevented from becoming'accidentally displaced.

Other and incidental objects will appear hereinafter.

In the drawing;

Figure'l is a perspective view showing a horseshoe equipped with toe and heel calks;

Fig. 2 is a sectional view on the line 2 2 of Fig. 1, looking in the direction of the arrows;

Fig. 3 is a sectional view on the line 3 3 of Fig. 2, looking in the direction of the arrows; and i f Fig. 4 is a sectional view on the line 1 -1 of Fig. 1, looking in the direction of the arrows, this view showing a slightly different embodiment-of the invention as comprehended in a heel calk.

Referring now more particularly to the drawing, I have. shown my present invention `in connection with a horseshoe lOfand shall first describe the invention as embodied in a toe calk. An oblong base block 11 is em` ployed and rising from said block is a sinuous calk member 1 2 preferably .integral with the block. The block is provided with a flat bottom face to seat Hat against the toe portion of the shoe and formed in the block at a point substantially midway between the ends thereof is a recess 13. transversely through the block to intersect this recess is an opening having angularly disposed portions 14 and 15 respectively, the portion 14 of the opening extending Extending 1921. Serial N0. 486,337.

obliq'uely with respect to the portion 15 and, as will be observed, theangularly disposed portions of the opening are formed to meet near one side .face of the block.

Upstanding from the body `block at opposr site sides kof the recess are studs 16 which snugly iit through ropenings formed in the toe portion of the shoe to accommodate the studs; and threaded through the shoe be-` tween said openings is a stud 17snugly `iitting in the recess 13 oit the `base block ofthe calk. `The stud 17 is provided with an encircling groove 18 registering with the opening through the base block 11, and drive-n through said opening to engagein said groove is alocking key 19. This key is preferably inserted .in the` portion. 14 of said opening when,fby. pounding upon the ykey, the key is. forced through the portion 15ofvthe opening. Thus, `the key will, due

to the angularity of theportionswlll and 15 of the opening, be bent longitudinally, and will thus be locked against laccidental displacement ironi the opening. As shownvin Fig. 2, the key lies partly within the opening through the base block and partly within said groove 18. The key will thus effectually'coact with the stud 17 for locking the calk upon the shoe, while the studs 16 will coact with the shoe for sustaining shearing.

stress upon the calk. The calk will accordingly be :firmly held in place. I-Iowever, when desired, the key 19 may be removed and the calk displaced, the stud 17 being, of course, also displaced.

In adapting the invention to a heel calk,

a few slight structual changes are made. An,

oblong base block 20 is employed a-nd.i'ising from the block is a sinuous or S-shaped calk member 21. The block is formed to seat flat against the shoe and is provided near one end with a recess 22. Extending from the block near its opposite end is a stud 23 snugly {itt-ing through an opening' provided in the shoe to accommodate the stud. Threadedthrough the shoe near said opening isa stud 24 having an encircling groove 25,r and formed through the base block to register with said groove is an opening 26 intersecting said vrecess and having angularly disposed portions corresponding to the angularly disposedportions14 and 15 of the opening of the toe calk. Driven through the opening 26 is a key 27 locking the calk to the stud 24. Thus, as will be seen, the heel calk is 'substantially identical with the toe vcalk with the exception that only one of the studs 23 is employed, while the recess 22 is arranged near one end of the base block instead of at a point sub-- stantially midway between the ends thereof as in the toe calk. U

Havingthus described the invention what is claimed as new is: y

l. In a device of the character described, a shoe stud, a calk fitting the stud, a vkey extending Within the calk coacting with the stud locking the calkv thereto, and means upon the calk bending the key whereby to loc-k the key against displacement.

2L In a device of the character described, a shoe stud, a ealk fitting the stud and provided with an opening having angularly disposed portions, and a key extending within said portions of the opening and bent thereby for locking the key againstdisplacement while coacting with the stud and' locking the calk'thereto. i 3. In a device of thecharacter described, a shoe stud, a calk having a recess receiving thestud, the calk being provided with an opening intersecting said recess and having angularly disposed portions, and a key extending within said portions of the opening and bent longitudinally thereby for locking the key against displacement while coacting with the stud and locking the calk thereto.

4. In a.y device of the character described,

a shoe stud having a groove therein, a calk having a recess receiving said stud, the calk being provided with an opening intersecting said recess to register with said groove and provided with angularly disposed portions, and a key extending within the angularly disposed portions of the opening bent longitudinally and engaging in said groove.

5. In a device of the character described, a shoe and calk one provided with a stud engaging the other and thelatter provided with an opening having angularly disposed portions, and a key extending within the angularly disposed portions of said opening and bent thereby for locking the key against displacement while coacting with said -stud for locking the parts together.

6. In a device of the character described, a shoe having an opening, 'a calk having a stud received in said opening and provided with a recess, a stud carried by the shoe and received in said recess, the calk being provided with an opening having angularly disposed' portions, and a key'extending .within the angularly disposed portions of said opening and bent thereby for locking the key against displacement while coacting with the latter stud for locking the partsv together.

In testimony whereof I aiiix my signature.
